Maybe that belt IS going to snap in the end...

Jaw hanging slack, James lifted his head and stared at his mother dumbfounded, barely processing what she was doing beyond the mind-numbing pleasure cursing through his body with her every move. His massive, swollen cum cannon was resting between Anne's prodigious bust, every vein standing out and pulsing with James' heartbeat. His nipples were so hard they hurt, tenting the over-endowed young man's makeshift top.

"Hnnuuh~?"

"Oh, little pervert..." Anne laughed, her body feeling so soft and warm against her son's shaft. "Has this ridiculous thing really reduced you to nothing more than a groaning mess? It seems I was wrong - you're worse than the main character! But at least..."

A slow, languid lick right around James' yawning urethra made him twitch and groan, hips bucking ineffectually and losing miserably against the enormous weight of James' gargantuan nuts and shaft.

"...at least you're proving to have a bit of staying power. Let's see how long it lasts, my naughty boy."

James could feel his melon-sized nuts swell, skin slowly pulling tight as every gentle lick, every teasing finger, every little move of his mother's body made the prodigious amounts of cum within his balls churn, slosh, multiply as his gonads prepared one load after the other - and the belt around his shaft held each and every one of them back. It creaked and groaned as James bucked his hips, **** for more stimulation, **** to cum, **** to finally crest that peak and find release, but Anne had chosen the right tool for the job, and no matter how much James' monstrous member swelled and his glans flared, the belt held out.

"I don't know if I should commend you or my choice of stopping you from being the quickshot that you are, little pervert," Anne murmured, hugging James' oversized tool against her body as she ran her tongue around his swollen cockhead. "But I do have to say, I like your determination. You could have opened the belt at any time, maybe even now, and yet you decided against it. It fills me with hope for your further training..."

A smile tugged at James' slack mouth - although he knew that his mother was partly mistaken. Lust and arousal had begun to sap his strength the second the belt had gone around his cock, and now, he was unable to lift a finger or move any muscle that wasn't twitching and bucking to thrust his hips. Not that this accomplished much, with the combined weight of his assets pushing him into the soft couch. All James could do was moan and breathe through this, completely at Anne's mercy - but somehow, he felt sure his mother would only push him as far as he could go. That, or the belt would give out.

"Mmmh, look at these..." Running her hands over James' massive, swelling nuts, Anne made her son groan lustfully as the hum of her voice traveled along his length. He barely noticed how smooth the skin of his balls had become, neither wrinkle nor hair left on the gurgling orbs as Anne's fingers danced about them. "They're so plump and juicy... and you actually managed to keep them under control with my help..."

That was definitely an exaggeration - in fact, it was probably the other way around. James was in no way in control over anything in this situation, he was basically just along for the ride. The supremely enjoyable ride. Lying limp against the backrest, James felt his eyes roll back into his head, mouth slack and body twitching weakly. Not being able to see what Anne was doing did change the situation, though; every new touch, every languid lick was a surprise that let his lust build ever higher, that took away another thought.

"Gosh, you're almost more cock than man now, naughty boy..." A finger trailed the entire length of James' shaft as Anne spoke. "Would you like that? Just be mommy's personal cock for as long as you live? Let her tease you and touch you and lick you whenever she wants, fuck her when she tells you to, and let her train you to be the perfect fucktoy?"

James was so far beyond being able to speak that he barely managed a somewhat affirmative moan, but Anne of course understood him and giggled before kissing her son's yawning urethra.

"I knew you'd like that, you perverted boy. You should be glad mommy needs exactly that - an obedient little fucktoy with a cock so large he can barely walk. And balls so fat they almost drag on the floor. Those massive, impractical tits are just a not-so-little bonus..."

Anne gently flicked James' desperately hard left nipple, letting the thumb-sized thing wobble up and down as he twitched weakly, cock straining and surging larger - and suddenly, a sharp tearing sound broke through James' **** panting.

"Oh my G--"

Before his mother could even finish her sentence, James felt the belt snap and finally, with a high-pitched shriek of pure lust and relief, he was hit with the combined pleasure of nearly a dozen orgasms - and Anne's face was hit by their combined jizz. James couldn't even move, not to thrust his hips, not to grab his cock to pump it for a bit more stimulation; he just felt his shaft strain and bulge again and again as impossibly thick baby batter was **** up and out by his gargantuan, twitchin nuts that were holding nothing back after what felt like an eternity, but couldn't have been more than an hour, considering the movie was still playing behind Anne.

Just as time had lost all meaning under his mother's teasing fingers, James was entirely unable to tell how long he had been cumming into Anne's face, coating it with layer after layer of spooge. She seemed frozen in surprise, or was simply unwilling to move and risk James ruining the TV behind them. Not that it helped much to diminish the mess raining down around her, Anne's face parting every thick glob jettisoned from the tip of her son's cock to let thick strands of jizz splatter onto the floor to the left and right behind her. Wet splats mixed with James' lustful screams until both finally petered out, his cock and balls still twitching as fat drops of cum kept bubbling up from James' glans.

"Wrgh..." As Anne tried to speak once the barrage had finally ended, the thick coating on her face made it nearly impossible. Raising her hands to wipe herself clean, or at least cleaner, Anne soon revealed a face that was surprisingly not furious, but at least a little annoyed. "Well. I didn't think that one try would be enough to properly train you, but this was still... surprising. It seems I have underestimated the role this ridiculous breasts of yours play. That is something I need to address soon... But for now, my naughty boy, I'm sure you realize that you will have to be punished for not warning mommy?"
